I have a 1997 tahoe sport with 142,000 on it, i have recently been looking around and have seen some very nice 1999 tahoe sports for sale with lower mileage. But i have never had any issues with my tahoe EVER! i dont know if it would be worth taking the risk or getting rid of it. But i have heard that the 1998 - 1999 tahoes are better....... what do yall think?
